Q. With reference to Magnetars, consider the following statements:
1.These are neutron stars with an ultrahigh magnetic field that are much stronger than the terrestrial magnetic field.
2.They are known for their slow rotation, often exhibiting a low degree of spin.
Which of the statements given above is/are correct?
Answer: A
Notes:
Explanation –
Statement 1 is correct. Magnetars are a type of neutron star that possess ultra-strong magnetic fields, which can be hundreds of millions of times stronger than the magnetic field of Earth. Neutron stars are the collapsed cores of massive stars that have undergone supernova explosions. Magnetars are a rare sub-class of neutron stars that have extremely powerful magnetic fields.
Statement 2 is incorrect. Magnetars are known for their rapid rotation, not slow rotation. They often exhibit high degrees of spin, with some magnetars rotating hundreds of times per second. This rapid rotation, combined with their strong magnetic fields, can produce intense bursts of energy, including gamma-ray bursts and X-ray bursts.
